PUSH-BUTTON.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed. February 6, 1919. Serial No. 275,367.

To all whom it may concern:

Be it known that Axnr. FERDINAND OLSSON WILCK, subject of the King ofSweden, residing at Surbrunnsgatan 51, Stockholm, in the Kingdom ofSweden, has invented certain new and useful Improvements in Push-Buttons, of which the following is a specification.

My present invention has for its ob ect an improved push button adaptedto be used on shoes, gloves and similar articles. The push buttonconsists as usually of two parts, viz., an upper part adapted to befastened to one of the leather members and containing a spring, and alower part adapted to be fastened to the other leather member andcontaining a hook or similar locking device which, when the parts are inlooking position catches a locking member on the other part and is heldforced against the same by the spring.

The characteristic feature of my invention now consists in this that thespring comprises a circular portion being fastened on the upper buttonpart and that at one place the said spring is formed to a tongueextending obliquely upward from the same in such a manner that, when thehook or other locking device is inserted through a hole in the bottom ofthe upper button part, said tongue exerts a pressure on the hook bothlaterally and downward. By this arrangement the advantages are gainedthat the spring as well as the fastening of the same will be very strongand durable, and, moreover, that the opening of the button can beeffected by merely displacing the upper button part to the side againstthe action of the spring a suflicient distance after which the tongue ofthe spring presses the locking member downward through the hole so thatthe parts are automatically separated without having the necessity ofpulling the parts from one another as is the case with the buttons nowin use.

The invention is illustrated on the accompanying drawing where Figure 1shows a sectional view of a push button. Fig. 2 is a plan view of thesame and Fig. 3 shows a modified form.

1 and 2 are the ends of the material, for

instance leather, in which the button parts 3 and 4 are fastened. Thepart 4: is provided with a hook or looking member 5 adapted to beinserted through an opening 6 provided in the bottom of the upper part.In this position the spring tongue 10 presses the hook 5 against theedge of the opening 6 and the hook is locked in this position by agroove 8 surrounding the same.

The spring consists of a circular part 7 over which the sleeve shapedportion 9 of the upper button part is bent down so that the spring isrigidly held fast between the bottom and the bent down portion of thesleeve. The spring is curved in the manner shown in Fig. 2 so that atongue 10 is formed on the same, said tongue extending from the circularportion 7 in an oblique direction upward. By this means the spring willexert a pressure on the hook not only to the side but also downward.When opening the button it is only necessary to displace the upper partlaterally (to the left in Fig. 1) against the action of the spring adistance suflicient for releasing the hook from the edge of the opening6. Then the hook is forced down through the opening by the pressure ofthe spring and the parts of the button are automatically separated fromone another.

The sleeve shaped part 9 is forced into a hollow head 13 indicated withdotted lines in Fig. 1. A similar head 12 of sheet metal is forced overthe sleeve shaped portion 11 of the lower button part 4. When pressedtogether the edges of the sleeve are folded down as indicated by dottedlines, whereby the button 12 becomes flat.

The form of embodiment according to Fig. 3 differs from that one shownin Fig. 1 only in this that the sleeve shaped portion is omitted andthat the button parts are attached to the leather by sewing.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

In push buttons the combination of two separate button parts, an openingin the bottom of the one part, a circular spring portion fastened in thesame, a spring tongue extending obliquely from said circular springportion, a hook member in the other button part to the side against theaction of button part adapted to be introduced the spring. 10 throughsaid opening, the spring tongue be- In testimony whereof I have aflixedmy ing located in such a manner that it exerts a. signature in presenceof, two witnesses.
